jam goals
JAM Goals

The primary goals of the Junior Agricultural Mechanics Project Show are:

  • Encourage, recognize, facilitate and reward learning and the development of skills through:
      • The design, construction and exhibiting an agricultural mechanics project and/or
      • Tractor Restoration.
  • Showcase the outstanding leadership, technical abilities and accomplishments of Texas youth.
jam goal
JAM Goal

For example – Building and exhibiting a blue ribbon project such as a trailer or restoring a tractor to almost new condition is not the primary goal – it is the by-product or evidence of learning.

Please use JAM as a teaching tool. A lot of the JAM rules and regulations are designed to help you in your teaching.

2008 show success and sadness
2008 Show Success and Sadness
  • The primary reason for our successes can be directly attributed to the outstanding work of our JAM committee with the leadership of Rick Laden and Alfred Carroll – Co-Chairs of the committee. As most of you know Mr. Carroll passed away, May 16 in Lytle. We all miss him. I want to thank all of you who wrote and called the family and expressed your condolences. They were very much appreciated.
  • Mr. John (LJ) Anderson with Zachry has been selected to replace Alfred. LJ has worked on the committee the past few years and will make a significant contribution to our show as one of the leaders of the committee.

The Entire Livestock Committee Leadership continues to support JAM.

  • Billy Schieberie, Chairman and Bill Jerman Vice Chairman.
  • Billy Feuge – Steering Committee member.
  • Livestock Office Staff- Yvonne “Bonnie” Ramirez in PT Mahoney’s office has helped our committee immensely. She is probably the one you talk to when you call.

Please thank these people when you see them. We could not conduct this show without their help and cooperation .

Check Sheets


check sheet used by judges to determine documentation
Check Sheet used by Judges to determine Documentation

Trailer, Tractor and Showmanship Check sheets are also found on Shell WEB.

Criteria are identified and explained in Premium List

  • We will continue to recognize and reward excellent Documentation.
  • As you know the criteria is different for Tractor documentation.
  • We asked judges to make comments on documentation on the critique sheets they give the exhibitor after judging their projects.

Two of the most important components of Documentation are:

1. Plans (Drawings) According to surveys from judges, drawings are still lacking in many respects. Remember the plans must be complete enough that the project could be constructed from them.

2. Bill of Materials – These need to be improved also. Remember they should be complete enough that anyone could take them to town and purchase the materials directly from them. I would suggest they be done on an excel spread sheet – another good learning skill.

suggestions help
Suggestions - Help

In slides that follow I am asking for your suggestions in a survey – questionnaire on topics for short courses to be carried out at Show.

  • In this survey I asked if you would present a short course or recommend someone that would.
  • In addition to a short course perhaps you or know of someone who would develop a presentation (maybe a Power Point) that I could post on my WEB page. For example Presentation could be on how to develop a Drawing or Bill of Materials.
2009 show changes a consideration to add event
2009 Show ChangesA Consideration to Add Event

We are not making many significant changes to the 2009 show from 2008. From input we have received from you teachers, exhibitors and parents, our 2008 JAM show was our best ever.

We are Considering Adding an Event - Short Course - to the 2009 JAM.

From Responses on our 2007 Survey, many suggested that they would be interested in attending a short course that would be conducted on Saturday while the projects were being judged. (See 2007 Survey Results on Shell WEB site.)

short course
Short Course

I am passing out a Seminar (Short Course) Questionnaire and asking that you respond and drop it in the box by the exit door as you leave.

From responses to this Survey perhaps we can determine if there is enough interest to warrant conducting Short Course/s and if so what topic/s would meet the greatest interest.

2009 Show Emphasis
  • We are emphasizing and focusing on the following in 2009 to reduce confusion and to reinforce consistency.
  • In doing so the educational value of JAM will be enhanced.
  • In fact you may consider some of the following for short course topics.
overview of special rules identified in premium list
Overview of Special Rules identified in Premium List

The following are explanations of selected new and existing Special Rules that are identified in the JAM Premium List. Please have exhibitor print out the premium book from the Rodeo WEB site They should read and study the 2009 Premium Book priorto beginning to design and build a project.

This will reinforce and augment the teaching learning process.

naming and entering projects
Naming and Entering Projects

Special Rule 1 in Premium List.

Even thought the leader AST/CEA must enter all projects – it is the exhibitors responsibility to see that their name is spelled correctly and their project is described according to guidelines identified in Special Rule 1.

Spelling and descriptions on Entry Form can influence Showmanship Award Consideration.

review of substitutions special rules identified in premium list rules 9 10
Review of Substitutions Special Rules identified in Premium List (Rules 9 & 10)
  • Projects Substitutions mailed to the Livestock Office and postmarked by January 15, 2009 = No charge
  • Project Substitutions made after January 15 must be made through livestock office = $20
  • Exhibitor Substitutions must be made through the Livestock Office. Substitutions will be allowed for only those reasons identified in the premium list (see Junior Livestock Show Special Rules in Premium List).
    • 1) Other School Activity
    • 2) Sickness
    • 3) More than one entry showing at the same time.
  • No exhibitor or project substitutions will be made on the exhibitor cards that have not been made first through Livestock Office.
review of special rules identified in premium list
Review of Special Rules identified in Premium List
  • JAM Special Rule 3 - Projects

Projects must be designed and constructed under the direct supervision and guidance of the CEA/AST.

Because more and more of the projects are being constructed away from the school shop (home shops) it is important that AST/CEA be responsible for entering and supervising the design and construction of the project. We encourage the exhibitor to include the leaders (AST/CEA) picture in the documentation that is submitted with the project. Most pictures should have the exhibitor/s picture in them.

review of special rule 17 safety transportation
Review of Special Rule 17 – Safety/Transportation

Mr. Charles Turner, DOT compliance officer at the show, will make all judgments regarding transportation codes as they relate to trailers and other towed vehicles.

Mr. Turner has a document on Trailer Statutes found under Additional Links on my WEB page. Be sure to have your students review this.

Please require your students to read and study this important rule, 17 Safety in the Premium List.

You may have noticed on the Questionnaire, Texas Transportation Statutes regarding codes for trailers may be a topic of interest for a short course.

Trailer Brakes

  • Trailer Brakes (547.402) Any trailer with a gross weight of 4,500 pounds but not heavier than 15,000 pounds, must have brakes – if tandem they should be on rear axle. (Any trailer with two 3000 pound axles would require brakes.)
  • There is a new Federal Law that requires brakes on both axles. I have not found it adopted by Texas at this time. We will adhere to Texas Code at this time.

asabe standards
ASABE Standards

Special Rule 18 ASABE

Standards included in the Documentation must be the latest. For example:

  • PTO standard S203.14 The most recent is FEB04.
  • Three Point Hitch S214.12. The most recent is DEC01.
objectives for accessing asabe on the web
Objectives for accessing ASABE on the WEB
  • A primary objective in addition to obtaining the information found in the ASABE Standards is to encourage students to become acquainted with professional organizations such as the American Society of Agricultural and Biological Engineers (ASABE).
  • Another objective is to enhance a student’s ability to search for answers to questions on the Internet.
  • Students may be asked questions from the standards. For example what is used to assign sizes of 3-point hitch’s?

Hitch Categories - S217 ASABE Document

You will notice some overlaps in PTO power for determining Category

Another teaching opportunity would be to show how to convert kW to HP [ 746 W = 1 HP (or) 0.764 kW = 1 HP ]

For example 48/.746 = 64 HP a Category 1 or 2 Tractor
